Benefits and Detractions of Venn Diagrams and Rules as Tests for Validity

1. What are the benefits and detractions of choosing Venn diagrams and rules as tests
for validity?
Answer.
The primary benefit of choosing Venn diagrams and rules as a test for validity lies in
its graphical presentation. The diagrams are the designs that are typically useful for
communicating information and are able to be presented in different forms (Shin, 1996). Due
to this reason people are able to understand the information easier or the visualization of
concepts are easier. However the kind of diagrams and rules raises complication when
dealing with many objects. Venn diagrams are considered for three most circles and has eight
regions which means the diagrams become difficult to interpret if there are more than the
limited of number of figures or diagrams.
2. Why are there two kinds of logic? Does each have its own advantage, or is one clearly
better than the other?
Answer.
There are mainly two types of logic- inductive and deductive as it broadly classifies
the formation of thoughts, opinions and judgements of logic or principle of correct reasoning.
The fundamental of a logical argument lies in its statement or proposition where the
propositions are used for building arguments (Shin, 1994). Among the two, deductive kind of
logic is better than inductive since complete evidence of the truth is provided in deductive
type of reasoning and leads to a specific and accurate conclusion unlike inductive.in case of
inductive, it considers only specific information and provides a broad generalization where
the results are probable and are usually established based on repeated experiences.
3. What exactly does the conditional mean, if not the usual "if-then"?
Answer.
The actual assertion of conditional means if an antecedent is true then the
consequence is also universal and true. Also any conditional consisting of a true antecedent
and false consequent is false. A Conditional statement is usually a compound statement “if a,
then b”, where ‘a’ is the antecedent and the ‘b’ is consequent (Strawson, 2017).
